Formula for Convert Australian Dress Size to American
The formula to convert Australian dress size to American dress size is as follows:
American Dress Size = Australian Dress Size - 4
This means that to convert an Australian dress size to an American size, simply subtract 4 from the Australian size.
For example:
- If you wear a size 12 in Australia, it would be equivalent to size 8 in the U.S.
- A size 14 in Australia converts to a size 10 in the U.S.
This formula applies to women’s clothing and is consistent for most brands. However, keep in mind that sizing can vary slightly between different manufacturers. It’s always a good idea to double-check size charts before making a purchase.

Dress size conversions are a common challenge for shoppers, especially when navigating different worldwide sizing systems. You might find it confusing if you are buying clothes from Australia but are used to American sizing. Understanding how to convert an Australian dress size to an American one is essential to ensure the right fit. This article explains the simple formula for the conversion and provides a practical tool for easy calculations.

Why is There a Difference in Dress Sizes?
Different countries have their own sizing systems for clothing, and understanding these differences is crucial when shopping internationally. For instance, Australia uses a size system that is roughly 4 sizes larger than the American system. This discrepancy arises from how each country developed its sizing standards.
In Australia, sizes are often based on measurements of the bust, waist, and hips. In the U.S., sizes tend to follow similar body measurements, but they have been calibrated differently over time. As a result, an Australian size 10 is often closer to a U.S. size 6.
The Impact of Different Size Standards
The impact of different sizing systems extends beyond just the clothing itself. Incorrect sizing can lead to frustration when shopping, as the fit may be uncomfortable or unflattering. Additionally, if you’re purchasing items online, a simple mistake in size conversion can lead to returns or exchanges, which adds time and effort to the shopping process.
Knowing the formula for converting Australian sizes to American sizes helps mitigate these issues. With this knowledge, you can make more confident purchasing decisions and avoid the hassle of returns.
Practical Tips for Converting Australian to American Sizes
- Use a Size Chart: In addition to the formula, most clothing brands provide size charts on their websites. These charts often list body measurements and corresponding sizes, which can help you find the best fit.
- Consider the Fit: Fit varies by brand, so a dress that fits well in one brand might not fit as comfortably in another, even if the size number is the same. Always check for the brand’s specific sizing guide if available.
- Look for Reviews: Many online stores provide customer reviews, which can give insight into how the clothing fits. If customers mention that a dress runs large or small, it can help you adjust your size choice accordingly.
- Try Before You Buy: If possible, try on the clothing before making a purchase. This is especially useful when you’re unsure about the fit, as trying on multiple sizes can help you make a more informed decision.
